Ah, I now see why: I hadn't really looked at the query, but now that I have, here are some of the problems:
1. Using median is a problem for many projects because many often start off (sometimes for years) with only a few developers before they really take off. The median() number for Elasticsearch was 28, but the max() is 49, which I suspect is closer to the current number.
2. Not everybody uses a pull request flow, and not everyone working on a project is a developer. You could have product managers, technical writers, engineering managers, etc, all working on a project and not opening PRs and you can have users just directly adding commits, especially when a project is young. The original query here for the kong/kong project shows a team size of 6, but if you remove event_type = 'PullRequestEvent' and switch to max(), you get 33.
3. Sometimes, parts of the project are kind of "elsewhere." e.g. Elastic employed a number of Lucene committers to help move Lucene along, Kong employed a number of folks that would e.g. commit/maintain OpenResty plugins which got incorporated in the build system, the docs live in separate repos in both cases, etc.
